helppp please I don't excel in this! A wave travels at 10m/s and has a wavelength of 2m. What is the frequency of the wave? If the speed of the wave doubles, but the wavelength remains the same, what is the new frequency?

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?
